The brain is the control center of the central nervous system. The brain is extremely complex. It contains more than 100 billion neurons, each linked to more than 10,000 other neurons by interconnects. This enormous number of interconnections provides a complex information processing system which is faster than todays fastest computers. This also enables the human brain to display intelligence.
A neuron is a fatty skin that coats the nerve cells. The coating acts as insulation and allows for fast bursts of signals around the body and brain.
Human brain performs the following tasks:
Anti Aging Diet
Warning signs of various diseases
Blood in urine
Warning signs of Cancer
Cancer Symptoms & causes
Cancer fighting foods
Warning Signs of heart attack
Warning signs of stroke
Warning signs of diabetes
Gout symptoms
Kidney stones
Kidney stones home remedies
Symptoms of Thyroid Problems
Normal Thyroid Levels
Thyroid Medication
Urinary incontinence
Urinary tract infection
Controls and regulates body temperature, breathing, digestion, blood pressure and heart rate.
Coordination of information from our various sensors such as eyes, ears, nose, etc.
Coordinates physical motion when walking, talking, standing or sitting.
Allows us think, dream, reason and argue.
Allows us to experience emotions.
Brain & Age
According to a research reported in 2008 by the Scientists at the University of California, our brain is fastest at the age 39 years and afterwards it declines rapidly due to the loss of neurons.
When the coating of the neurons, which acts as an insulator like an electric wire, deteriorates, the signals passing along the neurons in the brain slow down. This slows down the brain activity. After the age of 40 years, it becomes difficult or impossible for the body to repair the protective sheaths.
Delete Bad Memory
Researchers in SUNY Downstate Medical Center, Brooklyn have recently (2009) demonstrated that a single dose of an experimental drug containing a substance called PKMzeta caerase bad memories like emotional associations, spatial knowledge or motor skills. So far, the research has been done only on animals but scientists say it is likely to work in people.
Brain Parts
Human brain has the following parts:
Brainstem: The brainstem consists of an enlarged portion of the upper spinal cord known as the medulla, pons and midbrain. It controls the reflexes and functions of heart rate, blood pressure, digestion and urination; and limb movements.
Cerebellum: The cerebellum integrates information from the vestibular system that indicates position and movement and uses this information to coordinate limb movements.
Hypothalamus and pituitary gland: These control visceral functions, body temperature and responses such as feeding, drinking, pleasure and aggression.
Thalamus: It helps in sending information from the brainstem and spinal cord to the cerebral cortex.
Cerebral Cortex (also called the Cerebrum): It consists of the cortex, large fiber tracts and some deeper structures (basal ganglia, hippocampus, amygdala). It integrates information from all the sense organs, controls emotions and generates memory and thought processes.
